Cheap Direct Flights From Australia to Sri Lanka

Have you heard the good news that SriLankan Airlines is going to restart their direct flights to Australia. Yes it is true, SriLankan is going to start direct services between Sri Lanka and Australia from November 2017. They have decided to do this after acquiring brand new aircrafts from Airbus Industries. So when compared to other airlines, you will fly in more recently built modern aircraft with SriLankan.

SriLankan A340

SriLankan A333

With this new competition I think we will see better fairs to more Asian destinations. Introductory prices for the month of November 2017 from SriLankan seems very good as you see from some of the screenshots I have taken from the web site. Reserve your seats quickly by visiting SriLankan web site.

Enabling .NET 3.x on Windows 8 and Up

As you may be knowing, now you do not need to separately download and install .Net framework as we used to do with the older .Net frameworks. Since it is coming with Windows, you can just go to “Turn Windows Features On or Off” screen and enable framework you are after. It is simple right?

But in one of the machines it was not that simple for me. The installation tried to download files from Windows Update and was failing mentioning that it cannot get connected to Windows Update when the machine is connected to the internet without any issues.

The solution is to use DISM (Deployment Image Servicing and Management) tool to get it installed.

First you need to find a Windows setup media, a setup DVD or an ISO downloaded will work.

Then use the below command to enable the feature using a local source. Remember to open the Command Window as an Administrator of the machine.

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:E:\Sources\sxs

/Online – Targets the currently active and running OS.

/LimitAccess – If some installation files are missing, this will check Windows Update for the missing files. For not to check use /LimitAccess:True.

/Source – Is the location to find the source files, E: is my virtual drive which I mounted the previously downloaded Windows ISO.

If typed correctly, there will be a progress bar showing the installation progress.

Loy Yang Power Station – Traralgon Victoria – Australia

In my recent travels to Victoria I visited the Loy Yang power station. This power station consists of two sections named as “Loy Yang A” and “Loy Yang B” which was built in 1980s, both these plans are coal fired thermal power stations. Taken together these generate 4300 MW of power which is about 30% of Victoria’s current power needs and is the largest power station in Australia (when taken together). AGL owns and operates Loy Yang A and the adjacent coal mine.

There are no tours to look inside the power station but there is a picnic area where you can see the plants from a distance.

Removing all Partitions from a Disk

Today I thought of writing an article on how to remove all the partitions from a disk so you can re-use the disk.

If you tried removing existing partitions using the Computer Management (type computer management on the start menu to open it) tool in Windows you will find that, you can delete partitions by right clicking on the partition / volume and clicking on Delete Volume option.

image

However you will notice Computer Management is useless on some of the protected volumes since the options to work on them will not be available.In this case you will need to use the DiskPart utility in the Command Prompt.

image

In the Start type Cmd or Command Prompt to open a command prompt. Then type DiskPart, it is a powerful utility which can even work on protected volumes.

In my case, I would like to work on Disk 3 to remove all the existing volumes on it. Below are the steps required to clean the drive.

1. Select the disk.

List all the disks by typing List Disk, this will list all the disks connected and active at the time in your computer including the disks connected via USB ports.

image

Once you identify the disk you need, selection can be made by using the command Select Disk x. In my case Select Disk 3.

To confirm, list all the partitions on the selected list by using the command List Partition.

image

2. Delete all partitions by using the Clean command.

Ensure the proper disk is selected by Listing all disks by command List Disk, the currently focused disk will have a star at the beginning since recovering disks is not easy.

Type Clean and press enter. This will remove all the partitions from the disk. You can check the results by re issuing the List Partition command.

image

Close the DiskPart tool by entering the command Exit.

Computer Management will now show that the disk is uninitialized as below, Initialize the disk and create partitions / volumes as necessary to use it again.

Removing a Partition from a Disk

You can remove simple partitions by using the Computer Management tool found in Windows. Search for it on the Start menu to launch it.

But if it is a protected partition you will need to use the tool DiskPart. In the Start menu type Cmd or Command Prompt to open a command prompt. Then type DiskPart, it is a powerful utility which can even work on protected volumes.

To delete one partition, follow the steps.

1. List all disks by using the command List Disk.

2. Select the disk by using Select Disk x command.

3. You can confirm the disk by listing all the partitions on it by using the command List Partition.

4. Select the partition by using the command, Select Partition x command.

5. Delete the partition by command Delete Partition Override.

Override parameter needs to be passed if the partition is not a simple data partition.

You can confirm the deletion by re-listing the partitions on the disk by List Partition command.

SQL – The target principal name is incorrect. Cannot generate SSPI context.

Recently in one of my Virtual Machine (VM)s I received the above error message when trying to connect to a SQL Server which I used to connect on other times.

image

After having a look I found that the trust between my virtual machine and the domain was broken. You can find the status of the secure channel by using the PowerShell command Test-ComputerSecureChannel.

image

This will also be evident when you try to login to the computer using a domain account. It will generate the following message.

image[6]

To fix this you can try using the below methods.

1. PowerShell

Use the command Test-ComputerSecureChannel.

If your current login has the required access in the domain you can use the below command.

Test-ComputerSecureChannel –Repair

If you need to use another account than the current logged user then you need to use the –Credential parameter when calling the command.

Test-ComputerSecureChannel –Repair –Credential MyDomain\MyUser

2. Joining the domain again.

This will also get fixed by removing the machine from the domain and adding it back. Before removing the computer from the domain make sure you have access to a local administrator account on the computer. Otherwise you will not have a way to login to the computer.

This can be achieved by going to computer system properties,

  1. removing the computer from the current domain,
  2. restarting the computer.
  3. adding the computer to the domain again
  4. restarting the computer

To avoid the two restarts you can try using the following PowerShell commands.

$myPC = Get-WmiObject Win32_ComputerSystem
$myPC.UnjoinDomainOrWorkGroup("Account Password", "Account Username”, 0)
$myPC.JoinDomainOrWorkGroup("Domain", "Account Password", "Account Username", $null, 3)
Restart-Computer -Force

Open Live Writer – Plugin Not Working

While trying to setup and use the Code Plugin by Rich Hewlett I had trouble getting the plugin loaded into Live Writer. I did add the registry entry required as mentioned in the site, but still the plugin did not load.

Registry

Location - HKEY_CURRENT_USER\SOFTWARE\OpenLiveWriter\PluginAssemblies

Key - SyntaxHighlight_WordPressCom_OLWPlugIn

Value - C:\Users\Arjuna\AppData\Local\OpenLiveWriter\Plugins\SyntaxHighlight_WordPressCom_OLWPlugIn.dll

After a while I figured out that, when loading the plugin Live Writer encounters the following error.

"System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Users\Arjuna\AppData\Local\OpenLiveWriter\Plugins\SyntaxHighlight_WordPressCom_OLWPlugIn.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
File name: 'file:///C:\Users\Arjuna\AppData\Local\OpenLiveWriter\Plugins\SyntaxHighlight_WordPressCom_OLWPlugIn.dll' ---> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

This is due to a security feature of .Net Framework 4 or later. Before framework 4, if a DLL is downloaded (which is created in another computer), they used to run in full trust in the zone the assembly is running, but with frameworks 4 and later, downloaded DLLs will not run by default. To make them run, simply grant the DLL full access by going to file properties and selecting the Unblock checkbox in the security section as seen in the below image. This will apply to any plugin you download from internet. Also keep in mind to do this to DLLs you trust safe. Otherwise your computer will be unsafe.

To troubleshoot plugin and other errors you can refer to Open Live Writer log file located in C:\Users\Arjuna\AppData\Local\OpenLiveWriter\Open Live Writer.log.
